Roush Performance Cat-Back Exhaust, Side Exit (polished or black tips)

A cat-back exhaust replaces everything from the catalytic converter back to the tips. It changes sound and sheds a little weight - it is not a serious power mod on its own.

why this one — Roush does not publish a specific hp figure for this cat-back - like most exhaust-only upgrades, the real benefit is sound and a modest weight cut, not measurable power. You are paying for the Roush name and side-exit styling.
